Just bolt the plates (with the engine mounts attached to them) to the frame loosely, then slide in your engine. Once the engine is bolted to the mounts, let the engine settle in the frame. Once it is in, double check your trans mount...if everything lines up, bolt down the engine plates/towers. That is what I did, and it worked out great.

They make them adjustable for many reasons, slight frame differences for one, and ease of installation as well. You are just making it difficult on your own.
